摘要：
Sheet-like products are disclosed containing an additive composition. In accordance with the present disclosure, the additive composition is applied to a creping surface. The additive composition includes at least an aqueous dispersion containing a thermoplastic polymer. A base sheet is then pressed against the creping surface for contact with the additive composition. The base sheet is then creped from the creping surface causing the additive composition to transfer to the base sheet. In particular, the additive composition is transferred to the base sheet in amounts greater than about 1% by weight, such as from about 2% to about 50% by weight. The additive composition may further include a lotion, a debonder, a softener, or mixtures thereof.
